.ADJUSTING DEVICE FOR SATURATORS AND COATERS.

Application filed June 19, 1924. Serial No. 721,064.

This invention relates to adjusting devices for saturators and coaters.

In saturators and coater-s, for making prepared roofing, a continually moving sheet 1s caused to pass thru a receptacle or tub containing a saturant or coating material.

The sheet is usually formed in loops by passing over guiding rollers located near the top of the tub and then under guldmg rollers located near the bottom of the tub. It frequently happens that the sheet does not run true, showing a decided tendency to crawl toward one end of the upper rollers. 'Ihis tendency may be corrected by raising or lowering one end of the lower roller. It is desirable to make this adjustment while the machine is in operation so as to be able to determine when proper adjustment has been made.

Machines of this character contain many pairs of loop forming rollers, and it is highly desirable that each bottom roller shall be separately and independently adjustable, 1n the manner described. If effort be made to simultaneously adjust a plurality of bottom rollers, by. one instrumentality, by raising or lo-wering the ends of all thereof, one or more of the roller ends may be raised when it should be lowered, thus aggravating instead of curing the defect, While some of the other ends may require adjustment to a different extent or degree.

The invention herein disclosed provides means for adjusting each bottom roller separately and independently to vary the inelination of its axis.

The invention also provides means for moving, vertically, one end of the roller, up or down, in the smallest increments to accurately secure and maintain the proper position of the moved end.

Other and more specific objects and advantages will hereinafter appear from a con sideration of the following description, when taken in conjunction with the accompanying drawings, wherein A Fig. 1 is a plan view showing parts in section taken on line 1-1 o-f Fig. 2.

Fig. 2 is a broken away elevation Vof a saturator and coater showing parts in section.

Fig. 3 is an enlarged longitudinal section of parts about the hand operated shaft.

In all of the views the same reference characters are employed to indicate corresponding parts.

The drawings show only one unit of a saturator and coatel` comprising an upper roller 5 located near the top of the receptacle or tub 6, supported in bearings 7 and rotatably driven by gear 8. The sheet 9 to be treated, saturated or coated, passes over the upper roller 5 and below the lower roller 10 to receive the fluid or liquid treating material to be contained in the receptacle 6.'

The roller 10 is supportedon a shaft 11 in bearings 12 that are rotatable, to an extent, and carried by the rack posts l3-f13 to permit either rack to be raised or lowered with respect to the other to incline the axis of the roller 10, to some extent, to cause the sheet 9 to run true, over and under the rollers 5 and 10.

The racks or posts 13-13 are loosely tied together by a rod 14:. Its reduced ends 16 pass thru slots 15 made thru the lower ends of the racks orposts, and are held by the nuts 17. It'will, therefore, appear evident that the axes of the roller l() and of the tie rods 14 may be inclined from a horizontal plane when either of the racks is raised or lowered with respect to the other.

Both racks 13-13 may simultaneously be manually raised and lowered and to the same extent by the pinions 18-`18"'which are in mesh with the respective racks, when the pinions are rotated, whereby to lift the roller 10 into or above the horizontal plane occupied by the rollers 5, for the purpose tol thread the machine.

I have provided adjustable means for raising or lowering one rack, only, whereby to bring the roller 10 into a true horizontal plane or to incline it, more or less therefrom, to cause the sheet to run true about the rollers. The same means for moving both racks, as described, is adjustable to move one only.

The pinion 18 is secured directly to the rotatable shaft 19 by a key `20. The other pinion 18 is connected to or is a part of the sleeve A21. The sleeve 21 has an enlarged flange 22 as a part thereof o-r secured thereto. The sleeve is freely rotatable on the shaft- 19. A disk or flange 23 is secured to the shaft 19 at its hub 24 by a key 25. The disk 23 is larger in diameter than the flange 22 to carry a clamping ring 26.

To connect the sleeve 21 with the shaft 19, the bolt nuts 27 of the bolts 28 are tightened. This operation connects the pinion 18 to the shaft 19, so that the hand wheel 29 will rotate both pinions 18-'18 simultaneously and to the same extent to raise or lower t-he racks 13-13 alike.

The shaft 19 finds supportat one end in bearing 30.

The sleeve 21 is supported in bearing 3l. 'lhese bearings are provided in brackets or arms 32, secured to the supportiner posts 33 located outside the receptacle or tutb 6.

The sleeve 21 carries a brake drum 34, secured thereto by a key 35. A brake band 36 overlies the .drum and is tightened thereon by bolt 37 and handle 38, in a perfectly obvious manner. The brake band is secured to the bracket 32 by the part 39 which also may serve as another bearing for the sleeve 21.

When it is desired to change the axial position or inclination of a roller 10 of a machine, the individual brake band 3G re mains tightened, which prevents the sleeve 21 from being rotated. Nuts 27 are now loosened to disconnect the flange 22 from the disk 23, or to disconnect the sleeve 21 from the shaft 19. The hand wheel 29 is now rotated. This operation rotates the shaft 19 and pinion 18 to raise or lower the rack 13', by which operation the axial alignment of the roller 10 may be changed. This ad` justment may be made while the machine is running without interfering with its operation. The wheel 29 may be rotated to move the rack 13 in increments of very small gradation, and until the sheet 9 runs true, then the disk 23 and liange 22 are clamped together as before.

When it is desirable to raise both racks 13-13 at the same time it is only necessary to loosen the brake band 36, whereupon t-he hand wheel 29 will rotate the sleeve 21 and the shaft 19 as one. The racks may be held in selected positions by again tightening the brake band.

In machines of the character described, having a plurality of pairs of rollers 5 and 10, each such unit must be provided with the means disclosed for adjusting the in-v clination of the rollers 10 individually and independently of similar rollers of other unit-s, for the reasons heretofore discussed.

Having described my invention what I claim as new and desire to lsecure by Letters Patent, is

1. In a machine for treating moving flexible sheets the combination of a receptacle, or tub to contain the treating liquid; a pair of parallel, vertically movable racks in the tub; a roller supported near the top of the tub; a roller supported by said racks, near the bottom ends thereof; a air of rotatable pinions for lifting both rac is and means to hold one pinion and rotate the other to lift one rack for inclining the bottom roller.

2. In a machine for treating moving flexible sheets the combination of a receptacle, or tub to contain the treating liquid; a pair of parallel, vertically movable racks in the tub; a roller supported near the to of the tub; a roller'supported by said rac s, near the bottom ends thereof; a pair of rotatable pinions for lifting both racks; a substantially horizontal shaft extending to both racks upon which one of said inions is fixed; an independently rotatable slieeve overlying one end of said shaft to which the other pinion is fixed; means to clutch the sleeve to said shaft; means to hold the sleeve when disconnected from the shaft and means to rotate the sleeve and shaft when connected together and to rotate the shaft when disconnected from the sleeve.

3. In a machine for treatin moving flexible sheets the combination o -a receptacle, or tub, to contain the treatin liquid; a pair of parallel, vertically movab e racks in the tub; a rol'ler supported near the to of the tub; a roller supported by said rac s, near the bottom ends thereof; a pair of rotatable pinions for lifting both racks; a substantially horizontal shaft extending to both racks upon which one of said pinions is fixed; an independently rotatable sleeve overlying one end of said shaft to which the other pinion is fixed; means to clutch the sleeve to said shaft; means to hold one pinion while the other pinion is being rotated and means to rotate the shaft, sleeve and both pinions when connected together.
